zen of the United States, residing at Akron,

in the county of Summit and State of Ohio,

`have invented new and useful Improvements in Furnace Equipment, of which the following is a specification.

This invention relates to improved equipment for warm-air-heating furnaces.

Briefly, it frequently happens that in the heating of apartments it is advisable to employ a single register box suitably positioned in the apartment which usually supplies a sufficient current of air to heat the same without recourse to a plurality of such devices, each having its separate conducting pipe leading thereto; this arrangement is chiefly advantageous in large apartments, such as stores or places where the rooms are in open communication one with another, as it provides but a single opening in the ioorv or wall through which the hot air passes to the apartment and also through which the incoming cold air passes to the interior of the furnace casing.

Heretofore where single register-boxes have been employed, considerable difficulty has been encountered in insuring a sufficient current of cold air to the furnace due to the upward rush or current of heated air from the furnace which interferes with, tends to check and prevents the cold air from reaching the furnace, thereby destroying the circulation of air through the furnace casing and reducing the efliciency of a register box used in this manner.

The object of this invention is, therefore, to provide a single box provided with an apertured cover or register, said box communicating with the interior of the furnace casing and adapted to permit the free passage of both the heated air and the cooled air and effectually prevent intermingling of the two, or one current with the other.

With the foregoing and other objects in view, the invention consists in the novel construction, combination and arrangement of parts constituting the invention to be hereinafter specifically described and illustrated in the accompanying drawings which form a part hereof wherein is shown the preferred embodiment of the invention, but it is to be understood that changes, variations and modifications can be resorted to which come within the scope of the matter hereinafter claimed.

In the drawings in which similar reference numerals indicate like parts in the different gures, Figure l, is a plan view of a register box embodying this invention; and, Fig. 2, is a side elevation of a furnace and a register box therefor embodying this invention, and in operative connection therewith, the register and box being shown in vertical, central, transverse section.

Referring to the drawings in detail the reference numeral l denotes a furnace of any ordinary construction provided with an interior heater and a surrounding casing 2. The upper part of the casing is preferably conically-fashioned at 3 from which projects an upwardly-extending warm-air discharge-pipe et. Communicating with the lower part of the interior` of the casing 2 is a cold-air inlet 5, the upper end of which is preferably in a lower plane than the upper end of the discharge pipe 4.

The box which forms the primary object of this invention consists of side walls 6 and a lower wall 11. This lower wall 11 is provided with two openings, one to receive the discharge pipe 4 and the other the cold air inlet 5. Secured on the upper faces of the walls 6 is a register 10 provided with aplurality of openings 7 formed therein, as is the common construction. The marginal portions of the register constitute laterallyprojecting marginal fianges 8 to rest upon a Hoor 9 for holding the entire device in positio'n. The discharge pipe 4 for the heated air from the furnace extends through the lower wall 11 and approximately contacts with the register 10 and is considerably less `in area than the area of the register box,

and is preferably so positioned as to leave an open space around it for the passage of cold air passing through the register. The

upper end of the intake 5 for cold air is po-V as they enter the interior of the box they are free to pass around the member 4 without in any way coming, in contact with the current of air passing therethrough, and from thence pass downwardly through the inletto the lower part of the interior of the casing` 2 where they are heated and pass upwardly and out through the member 4.

It will be seen from the foregoing` that there can be no interference of one current of air with the other and thereby a constant and fresh supply of cold air is furnished to the interior of the furnace casing which insures a stream or current of heated air out through the discharge pipe 4.

The discharge-pipe i being immediately over the furnace receivesthe heated currents of air therefrom, and under ordinary circumstances becomes intensely hot; in fact, so hot that if brought into Contact with the floor or wall of a building not constructed of fire-proof material, there is considerable .liability of charring or burning the woodwork, so as to render the use of this type of register unsafe, but by positioning the discharge-pipe 4 in spaced relation with respect to the side walls 6 of the register box, the spaces between the member 4: and the side walls 6 constitute air spaces through Copies of this patent may be obtained for rive cents each, by addressing the Commissioner of latets,

which the cold air passes andy thereby prevents any danger of heat being transmitted or conveyed from the discharge-pipe 4; to

lthe fioor or wall, the space constituting an efficient safety zone for this purpose without the interposition of any non-heat-transf mitting material being necessary.

In combination, a register box for warmairA furnaces embodying side walls and a lower wall, the lower wall being provided with a pair of openings spaced from each' other,' an inlet-pipe for cold air communieating with one of said openingsadjacent one end of the box and having the end thereof engaging the side wall of the opening, and a discharge-pipe for hot air extendedy through the other opening and terminating above said first opening at the topk ofrs'aid box, said latter pipe being smaller than saidy box to provide a space thereabout for the free circulation of cold airrduring its pasp sage to Said inlet pipe, the hotair and cold air pipes being` so arranged to prevent mixing of hot and cold air in the register box. i

In testimony whereof I have hereunto set my hand.
